Ebook: Distant witness: social media, the Arab Spring and a journalism revolution

In this book, NPR social media chief Andy Carvin - hailed by The Guardian as 'the man who tweets revolutions' - offers a first hand recap of the Arab Spring. Part memoir, part history, the book includes intimate stories of the revolutionaries who fought for freedom on the streets and across the internet - stories that might have never been told before the days of social media.
